Actually no - most R9 290 do NOT work well if at all with a R9 290x BIOS - a few of the early ones do 'cause they used the same chip with a BIOS disablement, but that didn't last very long.

The R9 290x doesn't mine Ethereum any faster than the R9 290 does anyway - they're memory subsystem limited, not "number of cores" limited - the big help the Stilt BIOS does is to tighten up the memory timings a LOT making it effectively quite a bit faster (as well as turning off some of the parts of the card that aren't needed for mining, allowing for overclocking).

There are coins (and projects that can lead to coins) that would benefit if your R9 290 card *IS* one of the few that's actually a R9 290x under the hood - Ethereum just isn't one of them.

The Bitcoin network protocol was designed to be extremely flexible. It can be used to create timed transactions, escrow transactions, multi-signature transactions, etc. The current features of the client only hint at what will be possible in the future.

I know about the fork , but I thought it was not changing anything for us : as miner , we simply continue to mine Eth from our pools.Could someone explain me what I did not understand??

some miners decided to continue mining on the fork that did NOT return the stolen DAO funds, and are calling that chain "ethereum classic"

Whether it develops into anything meaningful is yet to be seen - presumably the attacker will have te ability to flood the market with a large quantity of ETC from the hijacked DAO funds

It will be interesting to see how this plays out - presumably hashrate follows the money so the two competing currencies will only be as strong as their valuation, with an obvious winner probably emerging within a few weeks.

be careful ETC is much lower in price then ETH make sure you know what you are doing.
